Peptide hydrolases of Antartic krill, Euphausia superba
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1985Abstract 1. 1. A survey has been made of the peptide hydrolase activities occurring in Antarctic krill, Euphausia superba. 2. 2. A major protein hydrolyzing activity in the pH range of 6–8, and a minor activity at pH 3–4, were detected. 3. 3. Temperature optima of approx.

Chitosans from Euphausia superba. 1: Solution properties
Carbohydrate Polymers, 1992Abstract A technological development of chitosan (copolymer of N -acetylglucosamine and glucosamine) is based on the knowledge of parameters such as composition. types of sequence, chain length and distribution. In addition to the sample source, these factors are related to preparation and purification methods.

Condition indicators for Antarctic krill, Euphausia superba
2023Antarctic krill use a variety of strategies to cope with, and thrive in the highly variable Southern Ocean environment. Despite much detailed information on its basic biology produced so far, the linkages between krill populations and the environment are yet to be systematically investigated. There is a practical need to have standardised indicators to

Aspects of Schooling in Euphausia Superba
Journal of Crustacean Biology, 1984ABSTRACT Divers observed schools of Euphausia superba off the South Shetland Islands and in Gerlache Strait near the Antarctic Peninsula. Euphausiids almost always occurred within the confines of dense schools swimming in one direction. Schools formed an infinite variety of shapes but usually were narrow in at least one dimension, so that individuals ...

Collagenolytic serine proteinase from Euphausia superba dana (antarctic krill)
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19911. A serine proteinase isolated from E. superba shows collagenolytic properties: it acts on collagens from Achilles tendon (type I and V) and reconstituted fibrils of calf skin collagen under conditions that do not denature the substrates. 2. At 25 degrees C and pH 7.5 the enzyme both splits the calf skin collagen in solution to the fragments TCA and ...

Histopathology of Antarctic krill, Euphausia superba, bearing black spots
Journal of Invertebrate Pathology, 2008Small black spots have been noticed on the cephalothorax of Antarctic krill, Euphausia superba, since January, 2001. To study the nature of the black spots, the krill were sampled in the winter of 2003, 2006, and 2007 in the South Georgia region, the Antarctic Ocean.

Development of eggs and nauplii of Euphausia superba
Polar Biology, 1984The development of eggs and nauplii was studied over 19 days. At 1.5°C nauplii hatched after 5 days. Abdominal spines changed their appearance successively during nauplius development, but no moulting was observed in the course of naupliar development. Moulting occurred between the nauplius and the metanauplius stage 13 days after spawning.
